1简单句、并列句、复合句
根据语法形式，即句子的结构，英语的句子可分为简单句、并列句和复合句。
1简单句
句型：主语+谓语
只包含一个主谓结构，而句子的各个结构都只由单词或短语表示。
They are playing baseball in the garden.
他们正在公园里打棒球。
Her brother and sister both are teachers.
她的哥哥和姐姐都是老师。
2并列句
句型：简单句+并列连词+简单句
(常见的并列连词有and，but，or)
并列句是由两个或两个以上的简单句连接而成。并列句中的各简单句意义同等重要，相互之间没有从属关系，是平行并列的关系。它们之间用连词连结。
My friend was at home， and we talked for along time.
我的朋友在家，我们谈了好长时间。
Her father is a doc** and her mother is a teacher.
她父亲是个医生，她母亲是个老师。
I liked the s**y very much but Li Ming wasn't interested in it.
我非常喜欢这个故事，可是李明却对它不感兴趣。
Hurry up，or you'll be late.
快点，否则你就会迟到的。
3 复合句
句型：主句+连词+从句;或连词+从句+主句(包含一个主句、一个或一个以上的从句，或只包含一个从句，但有两个或两个以上的主句的句子叫复合句。)
基本句型 五： S V O C (主+谓+宾+宾补) 此句型的句子的共同特点是：动词虽然是及物动词，但是只跟一个宾语还不能表达完整的意思，必须加上一个补充成分来补足宾语，才能使意思完整。 宾语补足语：位于宾语之后对宾语作出说明的成分。宾语与其补足语有逻辑上的主谓关系，它们一起构成复合宾语。 名词/代词宾格 + 名词The war made him a soldier. 名词/代词宾格 + 形容词New methods make the job easy. 名词/代词宾格 + 介词短语I often find him at work. 名词/代词宾格 + 动词不定式The teacher ask the students to close the windows. 名词/代词宾格 + 分词 I saw a cat running across the road. S │V(及物)│ O(宾语) │ C(宾补) 1. They │appointed │him │manager. 2. They │painted │the door │green. 3. This │set │them │thinking. 4. They │found │the house │deserted. 5. What │makes │him │think so? 6. We │saw │him │out. 7. He │asked │me │to come back soon. 8. I │saw │them │getting on the bus.
S V O (主+谓+宾)
此句型句子的共同特点是：谓语动词都具有实义，都是主语产生的动作，但不能表达完整的意思，必须跟有一个宾语，即动作的承受者，才能使意思完整。
这类动词叫做及物动词。宾语位于及物动词之后，一般同主语构成一样，不同的是构成宾语的代词必须是代词宾格，如：me，him，them等 S│V及物动词│O
1. Who │knows │the answer?
2. She │smiled │her thanks.
3. He │has refused │to help them.
4. He │enjoys │reading.
5. They │ate │what was left over.
6. He │said │"Good morning."
7. I │want │to have a cup of tea.
8. He │admits │that he was mistaken
： S V O C (主+谓+宾+宾补) 此句型的句子的共同特点是：动词虽然是及物动词，但是只跟一个宾语还不能表达完整的意思，必须加上一个补充成分来补足宾语，才能使意思完整。 宾语补足语：位于宾语之后对宾语作出说明的成分。宾语与其补足语有逻辑上的主谓关系，它们一起构成复合宾语。 名词/代词宾格 + 名词The war made him a soldier. 名词/代词宾格 + 形容词New methods make the job easy. 名词/代词宾格 + 介词短语I often find him at work. 名词/代词宾格 + 动词不定式The teacher ask the students to close the windows. 名词/代词宾格 + 分词 I saw a cat running across the road. S │V(及物)│ O(宾语) │ C(宾补) 1. They │appointed │him │manager. 2. They │painted │the door │green. 3. This │set │them │thinking. 4. They │found │the house │deserted. 5. What │makes │him │think so? 6. We │saw │him │out. 7. He │asked │me │to come back soon. 8. I │saw │them │getting on the bus.
S V o O (主+谓+间宾+直宾)
有些及物动词可以有两个宾语，如：give给，pass递，bring带，show显示。这两个宾语通常人为间接宾语;物为直接宾语。间接宾语一般位于直接宾语之前。一般的顺序为：动词 + 间接宾语 + 直接宾语。如：Give me a cup of tea,please. 强调间接宾语顺序为：动词 + 直接宾语 +介词+ 间接宾语。
如： Show this house to Mr.Smith. 若直接宾语为人称代词：动词+ 代词直接宾语 +介词+ 间接宾语。
如：Bring it to me,please. S│V及物│o多指人)│O(多指物)
1. She │ordered │herself │a new dress.
2. He │brought │you │a dictionary.
3.She │cooked │her husband │a delicious meal.
4. He │denies │her │nothing.
5. I │showed │him │my pictures.
6. I │gave │my car │a wash.
7. I │told │him │that the bus was late.
8. He │showed │me │how to run the machine.
S V P (主+系+表)
此句型的句子有一个共同的特点：句子谓语动词都不能表达一个完整的意思，必须加上一个表明主语身份或状态的表语构成复合谓语，才能表达完整的意思。这类动词叫做连系动词。系动词分两类：be, look, keep, seem等属一类，表示情况;get, grow, become, turn等属另一类，表示变化。be 本身没有什么意义,只起连系主语和表语的作用。其它系动词仍保持其部分词义。感官动词多可用作联系动词：look well/面色好,sound nice/听起来不错,feel good/感觉好，smell bad/难闻 S │V(是系动词)│ P His face │turned │red. 1. This │is │an English-Chinese dictionary. 2. The dinner │smells │good. 3. He │fell │in love.4. Everything │looks │different.5.He│is growing │tall and strong. 6. The trouble│is │that they are short of money.7. Our well │has gone │dry. There be 结构： There be 表示存在有。这里的there没有实际意义，不可与副词
there那里混淆。此结构后跟名词，表示(存在)有某事物 试比较：There is a boy there.(那儿有一个男孩。)/前一个there无实意，后一个there为副词那里。
